Gottlob Christoph Wecker was a German Kantor and flautist. He was born in Friedesdorf, Silesia, where his father was an organist. He attended the Gymnasium in Bautzen for 6 years and from 1723 studied jurisprudence at the University of Leipzig. He took private lessons from J.S. Bach between 1723 and 1728Grove/1729OCC. In a letter from February 26, 1727, J.S. Bach recommended him for the post of Kantor at the Jacobikirche in Chemnitz, but his application was unsuccessful. Two years later, on March 20, 1729, J.S. Bach gave him another letter of recommendation; this time he was appointed to a similar post at the Dreifaltigeitskirche in Schweidnitz, Silesia.

Gottlob Christoph Wecker's name appears at the end of the printed libretto of the Cantata Liebster Gott, vergißt du mich, BWV Anh 209, performed in 1727 at the same memorial service as J.S. Bach's Cantata Ich lasse dich nicht, du segnest mich denn!, BWV 157. It cannot, however, be assumed that Wecker composed the music.
